CAN YOU STAND HOW AWESOME THIS IS?

The trick, such as it is, is revealed when Monique shows us her hair from the back.

As you can see, there pink on one side and blue on the other, with a teeny sliver of blended purple in the center. So it isn't just ~rainbow mermaid realness~ from the front — it's also insanely beautiful from behind.

It also shows us how we mere mortals can achieve this mesmerizing transformation: part hair down the center and dye each half a different color. Deep-part your hair to one side, so that only one color is visible on top — and to change it, flip your hair and deep-part it to the OTHER side. Voila.

This isn't the first time we've seen color-changing hair.

Back in summer, this woman went crazy-viral for her platinum-to-brown transforming hair. And I have to be honest, even though I hate what bleach does to my head, this is so cool I'm like "Maybe it's worth it."
